Why do we need load list?
This first blogs is appropriately called step one loads list.
Figuring out how much power you need is a critical step that many people try to skip, designing a solar system without knowing your loads is like being asked,
How much gas do I need to drive without knowing what type of vehicle or how far you're driving?
For instance, if you needed to use a welder for a project, it may not make sense to design the whole system to be able to accommodate a tool that is only used once a year.
Having a generator available for occasional use makes good sense. Keep this option in mind when designing your system. This video series will cover the major steps of designing an off grid system.
Let's start with step one, analyzing your load. Let's go of the steps to determine the amount of power you need. Let's start with the loads analysis, unlike a grid type system where you can just base a system on how much power you want to upset, and then get the rest from the grid.
An off grid system needs to provide all of your power. With an awkward system, you need to take a good look at what you are powering and how long you need to power it.
Going off grid often takes changes to your lifestyle. It's not just as simple as saying, I'm tired of paying the electric company, I'm taking my whole house off grid,
You have to figure worst case scenarios, winter time, little to no sun for days, unless you're in a climate as long sunny days, all year round or this is for a seasonal house.
Most people who are doing a year round office system will have a generator available to pitch in the winter. I read a quote from an off greater who said, if it's gonna be a sunny day, I can cook waffles for breakfast. If it's cloudy, I have a bowl of cereal.
When designing the system, you can't just say it's an average size system. No such thing. You also can based on square footage of a house or cabin.
One cabin may have air conditioning and electric stove, water heater, electric washer, and dryer, fridge and freezer. The other may have LED lights in a laptop, which one is average?
Who is to say, do you think the same system will work for both cabins, even though they are both the same physical size?
No. You need to make a Complete list of every electrical device you'll be using, how much power uses and how long each day it'll be on?
Don't forget anything. All you listed equipment will have power label on it. Since votes times amps equals what?
You should be able to get all the Information you need off the labels.
